老师,下面的代码是按钮里的,帮我看看有什么问题,没有反应?
Dim Cols1() As String = {"订单明细编号对外","客户","品名大类","品名小类","坯布规格","缸号类型","投坯重量","投坯匹数","颜色","单双染","色号","卡注"}
Dim Cols2() As String = {"订单明细编号对外","客户","品名大类","品名小类","坯布规格","缸号类型","重量","匹数","颜色","单双染","色号","卡注"}
If Tables(e.Form.Name & "_table3").Rows.Count > 0 Then
    For Each r1 As Row In Tables(e.Form.Name & "_table3").Rows
        Dim dr1s As List(of DataRow) = DataTables("染色生产表").SQLSelect("缸号 = '" & r1("缸号") & "'")
        If dr1s.Count > 0 Then
            For Each dr1 As DataRow In dr1s
                For i As Integer = 0 To Cols1.Length -1
                    dr1(Cols2(i)) = r1(Cols1(i))
                Next
                dr1.Save
            Next
        End If
    Next
End If

老师,后来代码改成这样了,也达到预期作用,但是初学者,没有信心,看代码有没有改进的地方,谢谢?
